Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock'

By

If you are trying to connect mysql using password or without password
like mysql -uUSERNAME or mysql -uUSERNAME -pPASSWORD
and getting error:-  
Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

find first socket location
sudo find / -type s
my be location would be /tmp/mysql.sock

just go in the mysql file my.cnf
sudo nano  /etc/mysql/my.cnf

and do changes in scocket
port            = 3306
socket          = /tmp/mysql.sock

[mysqld_safe]
socket          = /tmp/mysql.sock
nice            = 0

Restart mysql, sudo /etc/init.d/mysql restart

And try login again mysql -uUSERNAME
Hope it will work.

 Command to know all the mysql variable
sudo mysqladmin variables

 To know mysql socket path
mysqld --verbose --help | grep ^socket

How to pass hash in Postman

By
By the looks of what you are trying to send, you need to change the Grape restriction, because destinations is an Array , not a Hash : requires : destinations , type : Array   You don't need the "destination" hash when sending the request: { destinations => [ { name => 'dest1' , other_attribute : 'value' , etc ... }, { name => 'dest2' , other_attribute : 'value' , etc ... }, { name => 'dest3' , other_attribute : 'value' , etc ... } ]}   This creates an Array of hashes. In order to send this through POSTMAN, you'll need to modify that destinations param your sending and add multiple lines in POSTMAN. Something like: destinations [][ name ] 'dest1' destinations [][ other_attribute ] 'value1' destinations [][ name ] 'dest2' destinations [][ other_attribute ] 'value2'

nginx: unrecognized service

By
The nginx: unrecognized service error means the startup scripts need to be created. Fortunately the startup scripts have already been written. We can fetch them with wget and set them up following these steps: # Download nginx startup script wget -O init-deb.sh https://www.linode.com/docs/assets/660-init-deb.sh # Move the script to the init.d directory & make executable sudo mv init-deb.sh /etc/init.d/nginx sudo chmod +x /etc/init.d/nginx # Add nginx to the system startup sudo /usr/sbin/update-rc.d -f nginx defaults Now we can control nginx using: sudo service nginx stop sudo service nginx start sudo service nginx restart sudo service nginx reload

Integrating to CloudFront service It’s simple to config and use CloudFront (a CDN service) for Rails app.  Just one thing from my experience, regarding to CORS issue on EB when your CSS want get loading font files or font-awesome. Because EB run your app with Nginx server serve public static files, then work around would be overwriting web server config in Nginx with  add_header Access-Control-Allow-Origin ‘*’  by crea
